Hi Stuart,Glad you like the blog!The video was brought to my attention by someone who thought that it contravened the Audiovisual Media Services Regulations, 2009

http://www.opsi.gov.uk/si/si2009/uksi_20092979_en_1

For example:

368 F 3:

(3) Advertising included in an on-demand programme service—(a)must be readily recognisable as such, and(b)must not use techniques which exploit the possibility of conveying a message subliminally or surreptitiously.

But... I think that it would count as a pop video, so not be subject to the same regulation. We'll see!
